Default oil pressure went to 120 and stayed

Went on a 500 mile trip 1/2 way there oil pressure went to 120 and stayed. Pulled off interstate and had oil changed,(use Mobil One 10W30). Turned around and headed back home was back to normal for very short time, went back to 120 and stayed all the way home. Took it to shop that installed my Magnuson supercharger and they replaced an oil snding unit,I think that'* what it'* called.Has not happened since but only drive 25 miles per day in sunny Florida.
B4 that incident oil pressure stayed on 40 now it fluctuates between 40 and 80. Been afriaid to take on extended trip.
Should I be worried or do you think that'* the fix?
